Express Cloud Foundry Actuator Middleware

Express middleware providing health and info endpoints for Cloud Foundry Apps Manager, inspired by Spring Boot Actuator. Current stable version is 1.8.0 (released May 2021), with maintenance-level updates addressing dependency vulnerabilities. Key differentiators: integrates natively with Cloud Foundry's Apps Manager UI, restricts endpoints to authenticated/authorized users, and works with the companion CLI to generate build info files. Compatible with Node 6+ (legacy engine requirement). Provides only health and info endpoints (no metrics, environment, or other Spring Boot actuator endpoints). Last release was over 3 years ago; no active development expected.
